Abstract |
This paper presents incipient fault diagnosis of synchronous generators using wavelet packet decomposition. Proper incipient fault detection techniques are required for synchronous generators because of their utilization in generating stations, petrochemical industries. Three phase currents are acquired from generator during fault condition. These currents are decomposed into approximate and detail signals to find energy of approximate signal and maximum energy of detail signals to diagnose the behavior of fault. Simulation results in MATLAB/SIMULINK are presented for various faults and for normal condition to find difference in energy ratio during healthy condition and faulty condition. Keywords— Wavelet, Incipient fault, WPD, MCSA, Energy Ratio. | |||||||||
